Storage box for pipette tips

A storage box for storing plastic pipette tips comprising:

• an electrically non-conductive frame part which is formed from two longitudinal walls and two transverse walls, wherein the longitudinal walls and the transverse walls laterally enclose an interior space and leave open a first opening on an upper side of the frame part and a second opening on an underside of the frame part,
• an electrically non-conductive support plate for plastic pipette tips, which is connected to the upper side of the frame part and covers the first opening,
• wherein the support plate comprises a plurality of bearing openings for inserting plastic pipette tips;
• and
• a plurality of stabilizing struts, which extend perpendicularly from an underside of the support plate towards the underside of the frame part,
• wherein the storage box comprises an electrically conductive pipette tip contact piece attached to the underside of the frame part, enclosing the second opening;
• the pipette tip contact piece extends parallel to the support plate and, is configured for contacting at least one plastic pipette tip inserted into one of the plurality of bearing openings, the pipette tip contact piece extends by a height, Hk, from the underside of the frame part towards the upper support plate without abutting the underside of the support plate;
• and the plurality of stabilizing struts extend to the pipette tip contact piece.
